broadest in front ; middle vertebrals broader than long. Plastron

For complete synonymy see Boulenger's ' Catalogue of Chelonians, 

 &c.' p. 112. 



Hab. Europe, S.W. Asia, and Algeria. In the Pleistocene the 

 range of this species in Europe was much more northerly than at 

 the present day, its remains having been obtained from the Pleis- 

 tocene of Mundesley. 



43001. The carapace; from the Pleistocene of Ghent, Belgium. 

 Mentioned by E. T. Newton in the ' Geol. Mag.' dec. ii. 

 vol. vi. p. 305. The pygal is wanting. This specimen is 

 adult, and is but slightly expanded posteriorly. 



Van Breda Collection. Purchased, 1871. 



43000. Cast of the entire shell of a smaller individual. The original 

 was obtained in the Yosges from beds which are probably 

 of Pleistocene age. The hinder part of the carapace is 

 much expanded. The specimen is abnormal in having 

 five regular costal shields on the left side, an imperfect 

 fifth one also occurring on the right.

49340. A number of imperfect costal bones ; from the Pleistocene 



of Zebbug Cave, Malta. Among these specimens one 

 (a) is the proximal portion of the 3rd of the right f side ; 

 another (6) is the distal part of the 2nd of the left side ; 

 another (c) the distal part of the 4th of the left side ; and 

 a fourth (d) the distal half of the 5th of the left side.

Genus DAMONIA, Gray 1 . 



Neural bones of moderate length, hexagonal, carinate, with short
